[−][src]Struct kas::widget::Splitter
A resizable row/column widget
Similar to kas::widget::List
but with draggable handles between items.
Implementations
impl<D: Directional + Default, W: Widget> Splitter<D, W>
[src]
pub fn new(widgets: Vec<W>) -> Self
[src]
Construct a new instance
This constructor is available where the direction is determined by the
type: for D: Directional + Default
. In other cases, use
Splitter::new_with_direction
.
impl<D: Directional, W: Widget> Splitter<D, W>
[src]
pub fn new_with_direction(direction: D, widgets: Vec<W>) -> Self
[src]
Construct a new instance with explicit direction
pub fn is_empty(&self) -> bool
[src]
True if there are no child widgets
pub fn len(&self) -> usize
[src]
Returns the number of child widgets (excluding handles)
pub fn capacity(&self) -> usize
[src]
Returns the number of elements the vector can hold without reallocating.
pub fn reserve(&mut self, additional: usize)
[src]
Reserves capacity for at least additional
more elements to be inserted
into the list. See documentation of Vec::reserve
.
pub fn clear(&mut self) -> TkAction
[src]
Remove all child widgets
Triggers a reconfigure action if any widget is removed.
pub fn push(&mut self, widget: W) -> TkAction
[src]
Append a child widget
Triggers a reconfigure action.
pub fn pop(&mut self) -> (Option<W>, TkAction)
[src]
Remove the last child widget
Returns None
if there are no children. Otherwise, this
triggers a reconfigure before the next draw operation.
Triggers a reconfigure action if any widget is removed.
pub fn insert(&mut self, index: usize, widget: W) -> TkAction
[src]
pub fn remove(&mut self, index: usize) -> (W, TkAction)
[src]
Removes the child widget at position index
Panics if index
is out of bounds.
Triggers a reconfigure action.
pub fn replace(&mut self, index: usize, widget: W) -> (W, TkAction)
[src]
pub fn extend<T: IntoIterator<Item = W>>(&mut self, iter: T) -> TkAction
[src]
Append child widgets from an iterator
Triggers a reconfigure action if any widgets are added.
pub fn resize_with<F: Fn(usize) -> W>(&mut self, len: usize, f: F) -> TkAction
[src]
Resize, using the given closure to construct new widgets
Triggers a reconfigure action.
pub fn retain<F: FnMut(&W) -> bool>(&mut self, f: F) -> TkAction
[src]
Retain only widgets satisfying predicate f
See documentation of Vec::retain
.
Triggers a reconfigure action if any widgets are removed.
